About this trial

The purpose of this study was to compare Scheimpflug corneal tomography findings in keratoconus and high myopic astigmatic eyes, as well as to establish the parameters distinguishing keratoconus from high myopic astigmatism.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

keratoconus patient

virgin clear cornea with high myopic astigmatism

normal cornea with high myopic astigmatism

Disqualifiers

patients had previous ocular surgery

ocular diseases rather than keratoconus

contact lens wearer

corneal opacity and corneal dystrophy

Trial population

The population represents individuals either have keratoconus or high mopic astigmatism and fit the inclusion and exclusion criteria to ensure proper comparison of corneal parameters .

Treatments tested in this trial

pentacam scheimpflug tomography
Other intervention
Pentacam tomography is not radiation-based. It uses Scheimpflug imaging, which involves a rotating camera that captures multiple images of the anterior segment of the eye. The system employs light-based technology to measure the front and back surfaces of the cornea, along with the anterior chamber and lens, creating a 3D model of the anterior eye structures. it uses light instead of ionizing radiation (like X-rays), it is considered safe and non-invasive for routine use in ophthalmology. * It was used to assess 23 parameters from topographic maps and 15 parameters from Belin-Ambrosio enhanced ectasia (BAD) display maps. * Parameters included keratometry readings, anterior and posterior sagittal curvature, corneal thickness, anterior chamber volume, and several indices from the BAD display map. * These parameters were analyzed to discriminate between keratoconus and high myopic astigmatism using Receiver Operating Characteristic (ROC) curves for diagnostic accuracy.

Treatment groups

66 Participants

are divided into 2 treatment groups

Group A: keratoconic group1 intervention

Group B: high myopic astigmatim group1 intervention

Trial outcomes

Primary outcomes

overall corneal mean difference thickness between keratoconus and mopc astigmatism

Scheimpflug imaging uses a revolving Scheimpflug camera to determine the front and back surfaces of the cornea, hence measuring the overall corneal mean difference thickness between keratoconus and mopc astigmatism as regarding central anterior chamber depth
